About 10–15% of urban schoolchildren overweight: Expert

Colombo, May 6 (Daily Mirror) - Raising concern over the prevalence of childhood obesity in Sri Lanka, Consultant Paediatrician Dr. Maheshaka Wijayawardena said 10–15% of school-aged children are overweight or obese in urban areas.

Speaking to the Daily Mirror, Dr. Wijayawardena said childhood obesity has emerged as one of the most pressing public health challenges globally, with a steady rise now seen in low-and middle-income countries, including Sri Lanka.

He noted that the country is experiencing a “double burden” of malnutrition, where undernutrition continues to exist alongside increasing rates of obesity, particularly in urban centres such as Colombo.

Dr. Wijayawardena explained that childhood obesity is measured using Body Mass Index (BMI) adjusted for age and sex, with values above the 95th percentile indicating obesity. He stressed the importance of early detection through regular monitoring.

He warned that the condition carries serious health consequences affecting multiple organ systems. These include a higher risk of hypertension, abnormal cholesterol levels, insulin resistance, type 2 diabetes, fatty liver disease, and respiratory issues such as sleep apnoea. Orthopaedic complications, skin conditions, and psychosocial issues such as low self-esteem, anxiety, and depression are also common among affected children.

“Obese children are more likely to become obese adults, increasing their risk of heart disease, kidney disease, and certain cancers later in life,” he said.

According to Dr. Wijayawardena, the rise in childhood obesity is driven by a combination of factors, including increased intake of processed foods and sugary beverages, reduced physical activity, excessive screen time, poor sleep patterns, and environmental changes linked to urbanisation. Genetic factors, while significant, often interact with lifestyle habits.

Dr. Wijayawardena stressed that addressing the issue requires a coordinated effort involving healthcare providers, schools, policymakers, and families. He highlighted the need for stronger school meal policies, regulation of food advertising, and improved urban planning to promote active living.

“Childhood obesity is not just about weight—it is a gateway to lifelong disease,” he added.
